Yes, I wanted to ask you the very same question ;-)
The reason I did not implement it immediately is that I am not quite
sure about the
format of said property and how should it refer to the series.
My current thinking is that it should be a simple comma-separated list
of series indexes, but that seems somewhat un-Pascalish,
so maybe you have a better idea?

BTW, please do not write much code depending on current TConstantLineDragTool
interface just yet -- I think I might change it substantially to a
more general one.
